My Husband And A Stent Placed In His LAD For

My husband and a stent placed in his LAD for a 95% occulsion. They had difficulty placing it. A month past now and he feels worse than before the procedure. Weak and SOB. The Cardiologist stopped his lopressor and lipitor and it helped a little but he still has no energy or strength. He doesn't want to go back to the cardiologist because he doesn't think he is being heard.
